The rupture of anterior cruciate ligament has been diagnosed by stress test, radiogram and diagnostic arthroscopy, but these methods have several disadvantages of lack of objectivity, exposure to radiation and risk of anesthesia. To eliminate these difficulties, the K-T 1,000 knee ligament arthrometer was used for the objective diagnosis in the injury of anterior cruciate ligament. We performed instrumented measurement of anterior-posterior laxity of the knee in 100 normal subjects by using the K-T 1,000 knee ligament arthrometer under the 15 lb., 20 lb. and maximum anterior pulls, and 20 lb. posterior push. The following results were obtained: 1. The mean anterior displacement at 20 lb.: 4.43mm The mean posterior displacement at 20 lb.: 2.30mm 2. The mean right knee-left knee difference in anterior displacement: 0.89mm 3. The mean anterior compliance index: 1.16mm So, we believed that a right knee-left knee difference and a anterior compliance index are sensitive measures of the integrity of the anterior cruclate ligament. And this test method was helpful for the diagnosis and objective recording in the injury of anterior cruciate ligament. This test method has following advantages: 1. There is no anesthesia risk. 2. The patient and examiner undergo no radiation exposure. 3. Diagnostic arthroscopy may be avoided. 4. Due to patient comfort, there is minimal muscle guarding.

BACKGROUND: There are reviews with regard to the treatment of pigmented nevi present on the palms, soles, and genitalia. One advocated that pigmented nevi on thesa locations should be prophylactically removed to avoid their tuture development into malignant melanoma, while the other believes that this is not practicable. OBJECTIVE: Our purpose was to determine the incidence rates and clinical characteristics and to discuss the management of pigrnented nevi, developed on these areas of the Korean men. METHOD: We examined 1,537 Korean men, between 19 and 21 rears old, to evaluate the pigmented nevi on their palms, soles, and genitalia. RESULTS: Atleast 1 pigmented nevus appeared in 314(20.4%) men on the palms, 189(12.3%) on the soles, and 117(7.6%) on the genitalia. The sizes(mean diameter) of nevi on genitalia, soles, and palms were 4.5mm, 3.1mm, and 2.3mm respectively. The color of the nevi was darkest on the penile shaft(4.3 point) and then glans penis(3.9 points), soles(3.2 points), palms(2.5 points) in decreasing orders of the points. Most of the nevi was consistent with type 1 by Levers clinical classification and their incidence were 357 on palms, 211 on soles, and 128 on genitalia. Among the 21 nevi of type 2, 13 nevi appeared on the soles, and noine of type 3 and type 5 were found. The distribution of the nevi on the palms was of a rather uniform and scattered pattern, whereas, on the soles, they were distinctly concentrated in the midfoot. Tkie nevi on the glans penis appeared larger and more irregular in outline than those on the penile shaft. CONCLUSION: The plantar nevi were larger, darker, and had greater incidence of elevated type compared with the palmar nevi. From this observation, particular attenticn should be paid to the presence of pigmented nevi on the soles.

Hand dermatitis of silk industry workers had been a troublesome problern for a long time. It was said the cause was due to toxic reaction by denatured pupae and physical reaction from high water temperaturc. During Augnst and September 1973, patch test was performed with pupa and cocoon to 680 workers in 4 separate silk factories in order to persue the factors which may cause their hand dermatitis. Among 475 workers who had performed first patch test, only 12 workers in one of four factories showed positive reaction in pupa and we came to know that only that factory had used formalin in order to protect denaturation of pupae and cocoons. Second patch test with pupa and 1% formalin was repeated to 130 subjects including 6 of 12 positive cases in the first pateh test. Five Subjects shosved positive reaction in pupa, also 5 in 1% formalin and 2 of them showed positive reaction in both pupa and 1% formalin. In the second patch test, 3 of 6 who had been positive in pupa at first patch test were positive at pupa. It seemed to be that toxic or allergic theory is not enough to explain clearly the cause of hand dermatitis in silk industry workers. Further stucly is necessarv to elucidate how the silk fiber, water temperature and parasites in the pupa and cocoon contribute to the hand dermmatitis.

Dermstomyositis is a disease mainly of the skin, muscle and blood vessels in which erythematous and edematous changes in the skin are associated with muscle weakneas and inflammation. In adult the disease is commonly associated with underlying malignancy or reticulosis. A 23 year-old male had generalized weakness, intermittent fever, myalgia and purplish red patches on the face. Diagnosis of dermatomyositis was established by clinical manifestations, electromyogram, histologic findings of skin and muscle. He was treated with systemic steroid, with some improvement. Seven months after the onset of dermatomyositis, ecchymoses was noted on the eyelids and forearms. Bone marrow aspiration showed many immature lymphoblasts, characteristic of acute lymphocytic leukemia, He was treated with systemic steroid and vincristine, but no favorable effect was noted. He died of sepsis due to retal abscess on the 34th day in the hospital

The goal of total knee replacement is to relieve pain, to stabilize joint movement and to correct deformity. It is indicated for patients with rheumatoid arthritis, osteoarthritis and severe post-traumatic arthritis. The author analyzed 71 patients(106 cases), who received the PFC type of total knee replacement from August 1992 and the results were as follows; 1. Among the 71 patients, male was 8 patients and female was 63 patients whose average age was 56 years and average follow up period was 24 months, ranged from 8 months to 3 years 8 months. 2. Rheumatoid arthritis was the most common cause with 31 patients(56 cases) followed by osteoarthritis with 39 patients(49 cases). There was also one patient(1 case) that showed bony union of the knee due to old tuberculosis. The average duration of the illness was 12 years and the average weight of the patients was 57.7kg. 3. Flexion contracture decreased from an average of 21 degrees to 5 degrees after the operation. The range of motion increased from an average of 92 degrees before the operation to 117 degrees afterwards in cases of rheumatoid arthritis and decreased slightly from 108 degrees to 106 degrees in cases of osteoarthritis. 4. The tibiofemoral angle was corrected from an average 1.5 degrees varus before the operation to an average 6.7 degrees valgus after operation. Eighty seven percent of patients with rheumatoid arthritis showed valgus deformity and seventy eight percent of degenerative osteoarthritis patients showed varus deformity preoperatively. 5. Radiographically, the joint line position shifted an average 2.3mm in rheumatoid arthritis and an average 0.3mm in osteoarthritis. The component position, the femoral flexion was an average 89.6 degrees in the anteroposterior view, an average 87 degrees in the lateral view. 6. The thickness of the patella measured in the operating room of 61 cases was an average 21mm and after resection of patella, the remaining bone measured an average of 13.6mm. 7. To achieve soft tissue balance, 29 patients(33 cases) underwent medial stripping and 23 patients(30 cases) had patella lateral release. 8. The Insall Knee Rating Score was used to evaluate the results. The results were 69 cases excellent, 33 cases good, 3 fair and 1 poor. Ninety two percent of the patients had good or excellent results in average 24 months follow-up. 9. The complications consisted of one case of delayed deep infection, one case of patellar subluxation and one case of supracondylar fracture of the femur.
